What is the difference between submission and surrender?
I want to offer one explanation. Both are about letting go of control, and the difference is where you go instead. In surrender, you journey into yourself. In submission, you journey into the will of another.
This makes surrender into an introspective experience, while submission into an interpersonal experience. In submission, you dedicate yourself to another being, and your attention remains full on their will. While in surrender you dedicate yourself to your present experience.
In surrender, your suffering is relieved by not comparing the present situation, to the past or future. While in submission your suffering is relieved by replacing your will with the will of another.
This distinction is important greatly when playing with polarity in control and power.
